ration of Maine "Application March 19 8 Claims.

The present invention relates to loom temples and has more particularreference to temples which are provided with filling parting means foruse on automatic filling replenishing looms.

vIn looms of the type mentioned, the filling replenishing operationleaves filling ends projecting from the selvage of the cloth, and thetemple is provided with parting mechanism for trimming these fillingends adjacent the selvage. The actual parting, means may be of differentforms but preferably includes a movable cutting blade for cutting thefilling. It is to means for actuating the parting means, as a cuttingblade, that my invention pertains.

Prior to my invention, filling parting means of the class describedusually included a rocking and sliding cutting blade having a dependingheel adapted to be struck by the lay. This, and

other types of parting means, are subject to the disadvantage that theywear out rapidly, and thus require considerable attention. Furthermore,they must be constructed and adjusted with a high degree of accuracy,which detracts from their commercial value.

I propose to provide a filling parting means, and operating meanstherefor, which shall not be subjected to repeated heavy blows by thelay and which accordingly shall not be subject tov excessive Wear. Ifurther propose to so design such parting and operating means as todispense with any necessity for extreme.accuracy in construction oradjustment.

To the end mentioned, I have devised, and herein disclose, areciprocating temple provided with a movable cutting blade operated byinertia-activated means which is'rendered eifecti-ve by reciprocation ofthe'temple. Preferably, the operating means consists of a weightedelement on the temple in such manner as to tend to remain stationary,solely through its own inertia, -while the temple reciprocates. Theinertia-induced relative movement between the weighted element and thetemple may be utilized in a variety of ways to operate the movablecutting blade.

The accompanying drawings illustrate three preferred embodiments of myinvention. Refer-' ring to the drawings:

Fig. 5 is a view similar to Fig. 4 but showing 1 a second embodiment;and

Fig. 6 shows a still further embodiment of the invention.

The loom to which my invention has been applied is conventional indesign and accordingly I have illustrated. only the breast beam 1 andthe reciprocating lay 2. The breast beam ex-. tends across the front ofthe loom in the usual manner and the lay reciprocates forwardly andrearwardly, toward and from the breast beam. The 'warp threads W arewoven with filling to form cloth C which feeds toward the front of theloom. a

Referring to Figs. 1-4, a slide 3 is mounted on the breast beam tosupport a temple housing 4. A temple bar 5 is slidably mounted in thehousing 4 forreciprccation forwardly and rearward ly of the loom. Thetemple is yieldingly, urged rearwardly by a coiled spring 6 within thehousing and is moved forwardly when a depending heel 7 onthe bar isstruck by the lay; A laterally extending temple head 8 may contain theusual temple rolls 9 journalled on a roll pin 10. The temple and templehead are of usual. construction except as modified to accommodate thepresent filling parting means and its operating means. The temple head 8is provided with a recess or cavity of a shape shownon the drawings, toreceive the filling parting means and the aforementioned operatingmeans. In the embodiment illustrated by Figs. 1-4 a ledger blade 11 issecured to one vertical wall of the cavity as by screws 12, 12. Therear, vertical edge of the ledger'blade is notched at 13. to receive andsupport the filling f which extends from the cloth selvage. The loweredge 14 of the notch 13 may be left blunt,to serve merely as a supportfor the filling or may be sharpened, to assist in the cutting thereof.

The movable cutting blade 15 is carried by a hub 15 (Fig. 4) which isloose on the roll pin 10. The cutting blade 15 oscillates freely aboutthe axis of the rollpin and. is not subjected to any heavy stresses.Consequently, this blade can be made of thin steel and provided with avery sharp cutting edge. T

In the embodiment under discussion the operating means for the movablecutting blade is comprised simply of a weighted element 17 formedintegral with the hub 16-and projecting upwardly and forwardlytherefrom. A stop screw 18 engages the element 17 to limitcounterclockwise movement thereof. The weighted element is comprised ofa fairly heavy mass of metal positioned so that its center of gravity iswell above the axis of the roll pin 10.

The force of gravity holds the weighted element and the movable cuttingblade in the position shown at all times except during the period orreciprocation of the temple. When the lay strikes the temple heel andthe temple is suddenly moved forwardly the inertia of the element 17causes the latter to tend to remain stationary. Since the element ispivoted to the roll pin it cannot remain stationary, but will moveclockwise relative to the temple, about the roll pin. Thus, when thetempleheel is struck by the lay the movable cutting blade is moved downonto any filling which is positioned in the notch 13 and such fillingwill be severed. Return of the temple rearwardly by the spring 6 resultsin the cutting blade and weighted element being restored to normalposition.

It will be apparent that'neither the inertiaactivated element 1'7 nor,the movable cutting blade is subjected to any great strain, whereforethe likelihood of their becoming worn out or broken is very small.

It will likewise be apparent that other inertiaactivated means may beutilized in different manners to operate a filling parting device. Twoof such other means will now be described.

Referring first to Fig. 5, the temple bar 19, temple head 20, heel 21,roll 22 and roll pin 23 are similar to those above described except thatthe cavity in the temple head is modified as will be apparent. Only ashort ledger blade 24 is used, and the movable cutting blade 25 isformed integral with the hub which is journalled on the roll pininwardly of the roll pin support 26. Extending forwardly from the hub ofthe cutting blade is an arm 27 which contacts the weighted element 28.The element 28 is pivotally suspended from a pin 29 in the temple head.

The arm 27 is sufiiciently heavy to overbalance the blade 25 and thusremain in contact with the weighted element. It is thought that themanner in which the inertia of the weighted element causes relativemovement between the latter and the temple and the manner in which suchrelative movement is caused, by the connection 27, to operate thecutting blade will be obvious.

Referring to Fig. 6, the temple bar 30, head 31, and other partsincluding the roll pin 32, ledger blade 33, cutter blade 34 and arm 35are identical with corresponding parts in Fig. 5. The inertiaactivatedelement 36 is'in the form of a block which is slotted at 37 to receive apin 38 in the temple head. The block is slidably supported by the pinand by a ledge 39 on the temple head. An upwardly and forwardly inclinedcam surface 40 on. the block is engaged by the connecting arm 35.. Alight coiled spring 41 is positioned between the temple head and theblock to prevent the latter from jarring forwardly from the vibration ofthe loom. This spring does not operative- 1y modify the operation of theblock, but only prevents it from becoming misplaced.

The mode of operation of the device of Fig. 6 is obvious and requires nofurther discussion.

Having fully disclosed preferred embodiments of my invention, I claim:
